Thats really awful to hear, I' cannot believe they are not doing anything to sort it. When i got my car i noticed a deep scratch that ran from outside in, like they had passed something through the wondow, i bought it brand new, and rang as soon as i nooced it, my local dealer sorted it out immediately and i've had no trouble with anything since. I think its appalling the service you're getting. Is there really nothing you can do. What about threatening to take them to court?
